INSULATED HANGER.

Apphcat ion filedApril 28,

To all whom it may concern:

Be it known that I, LOUIS Srmnnnaonn, a citizen of the United States,and a resident of the city of New York, borough of Brooklyn, in thecounty of Kings and State .of New York, have invented a new .andImprm'ed Insulated Hanger, of which the following is a full, cleaiyandexact description.

My invention relates to insulated hangers, admitting of general use, andparticularly adapted to be employed for supporting electrical railwaytrolley wires; my object be ing to produce a type of hanger of a simpleand inexpensive construction, strong and durable and of ahiglrelliciency, which shall be capable of sustaining severelateralstrain without breaking, and the outer metallic case of which.shall be of such shape as to fully protect the insulation which iscontained within thesamc from blows which it may receive from amisplaced trolley,.which may operate to injure the insulation; my more.particular objectbeing, however, to produce a type of hanger in whichthe melting of the insulation, due to leakage from heavy cur rents orother causes, is unable to cause the" line. wire or other conductorsupported by the hanger, to separate from the same or to tionspreferably being integral.

fall to the ground.

I do not desire to limit myself to the particular form or constructionof the parts as herein shown and described, as variations of detailswill readily occur to those skilled in this art, without departing fromthe spirit and scope of my lnvention.

Reference is to be had to the accompanying drawings, forming a partofthis specification. in which similar characters of refercnce indicatecorresponding parts in all the figures.

V Figure 1 is a substantially central section through the insulatedhangerof my invention; Fig. 2 is a horizontal section upon the line 22of Fig. 1, looking in the direction of the arrow; Fig. 3 isfafragmentary view of a modified form of supporting member; and Fig. 4: isa substantially central section through the hanger shown in Figs. 1and'2, but in which the insulation has melted.

A substantially bell-shaped member 1 is provided with hanger portions 2,3,. bent at 1, 5, for the purpose of engaging a suspension wire, thebell-shaped and hanger por- Integrally connected with the bell-shapedmember 1 are Specification of Letters Patent.

' a common center, as indicated in Fig. 2. ,A

metallic bolt 10 is provided with a head11, with a shoulder 12, and witha threaded por-.

.tion 13,.as indicated in Fig. 1. The body portion or stein of theboltWis-comparatively small, so as to be able toipass freely between thelugs6,7, '8, 9, while the he'ad 11* passdown is of such size as to beunableto ward between these lugs. Packed-within the bell-shapedme'mber 1 is aquantity of insulation 14l, in which the "bolt 10 is preferablyembedded, as indicated. The extreme upper portion of in'Fig. 1. thebell-shaped member- 1 'is provided witli'a threaded neck 15, and isengaged by a.

threaded cap 16. This .cap is preferably made convex, as indicatedinFig. l. In the form shown in Fig. 3,- the bellshaped portion 17 hassubstantially the form abovedescribed, with the exception that the neck18 is smoothv and is beveled internally as shown. Where this form ofbell shaped piled up in thecenter so as to form a rotund member is used,theinsulation is merely portion 19. XVhe're either form is -used,the

purpose in having theupper portion rotund is to avoid injurious effectsdue to the acci-. dentaLblows of the trolley pole, and to shed rain,snow, etc, more readily,

In operating overhead, trolleys, the trolley pole frequently slips,owing to the fact that the trolley misses the wire,- and when broughtdown often-injures the insulators and hangers disposed along the routeby insulation llbemeltechas it frequently is owing to short circuitingor heavy currents, the bolt 10 will simply descend so thatthe head 11will rest upon the lugs 6, 7-, 8,9. This gives the bolt 10, andconsequently the clip to be secured thereto by means of the thread 13, afirm support from which it can only be released by the melting of the metallic support, consisting of the'bell-tshaped I member 1, or the ban ermembers 2,

Having thus described my invention, I

claim as new, and desire tosecure by Letters Patentf,

An insulated stantially bell-shape support open at its hanger,comprising axjsubtop and provided at its bottom with a flange cuppedslightly inward, said support being further provided with lugs disposedintermediate its upper edge and its lower edge, said lugs forming acircle,- a body portion of insulating material mounted within saidbell-shape support and engaging said lugs and said lower edge, said bodyportion of insulating material extending through the open top of saidbell-shape member and provided above said top with a portion of slightlygreater diameter-than the internal diameter of the opening, and ametallic bolt partially embedded within said body portion of insulatingmaterial, said bolt having abody portion extending intermediate saidlugs, and provided with a head disposed between said lugs and the top ofsaid support, said bolt being further provided with a 'flange partiallyembedded Within said body portion of insulating material and beingfurther provided with a threaded portlon extending from said flange.
